BEDSTEAD.

SPECIFICATION formingpart of Letters Patent No. 641,443, dated January 16, 1900.

Application led March 31, 1899. Serial No. 711,314. (No model.)

To all whom it may concern: l

Be it known that I, GUsrAv ELSTERMANN, a subject of the Kin g of Prussia, German Exnperor,'residing at Osnabrck, in the Province of Hanover, in the German Empire, have invented new and useful Improvements in Bedsteads, of which the following is a specification.

The subject of the present invention is a bedstead the sides of which can be raised vertically for the purpose of protecting the body of the person using the bed from draft, exposure through displacement of the bedclothes and the like, and also to prevent the possibility of falling out. The sides when in their lowered position admit of a person getting into and out of bed without trouble.

The improved bedstead may be of the same general form and dimensions as those already in use.

The invention is shown on the accompanying drawings applied to a wooden bedstead.

Figure 1 shows a side elevation of the improved bedstead, the sides being in their lowered posit-ion. Fig. 2 is a section showing one of the head-posts and sides, taken on the line fr oc, Fig. l. Fig. 3 is a side elevation, similar to Fig. l, of the bedstead, the sides being in their raised position. Fig. i` is a section similar to Fig. 2, showing one of the head-posts and sides, taken on the line y y, Fig. 3.

The bedstead may in general construction resemble .those at present used. The four posts g h, however, are connected together by a suitable rigid framework f, and each post is provided with a vertical groove k or equivalent guideway. The sides of the bedstead a are provided with pins t', adapted to slide in the said grooves lo, so that the sides a may be moved up and down in the bed-posts. To the frame f is pivoted at the point c a bell-lever lc, one arm of which is jointed at c2 to an arm e, pivotally secured to the side a .of the bedstead at e'. The other arm of the bell-lever c is formed as a long hand-lever b, capable of being moved freely to and fro. To this lever at the point d is pivoted a connecting-rod d, the other extremity of which is pivoted at cS to the bell-lever c4, pivoted at c5 to the frame f. The second arm of the bell-lever c4 is jointed at c6 to the arm e2, pivotally secured to the side a of the bedstead at e3.

In the ordinary lowered position of the bed sides the lever system takes up the position shown in Fig. 1, the hand-lever b projecting above the side. If now it is desired to raise the sides of the bedstead, the leverb is grasped and pushed forward toward the middle of the bed side. This causes the bell-lever c to turn on its fulcrum, whereby the arm e, and with it the side a, is raised. The motion of the lever b simultaneously causes the rod d to turn the bell-lever c4 on its fulcrum e5, so that the arm e2, and with it the side a of the bedstead, is raised. Thus by a single manipulation of the hand-lever b the bed side a is caused to rise to its elevated position. By a reverse movement of the lever b the side ci may be lowered, as will be clearly understood. Such a system of levers b c e d c4 e2 may be applied to each side of the bedstead and, if desired,A

connected by suitable rods, so that the movement of one of the levers b on the one side of the bed may operate both systems of levers, and thus raise both sides of the bed simultaneously.

Having now fully described my invention, what I claim as new, and desire to secure by Letters. Patent, is-

A bedstead comprising a side or sides a, head and foot posts g h, having Vertical guideways k to receive said side or sides, a rigid framing f extending between said posts and a lever mechanism attached at one or both sides of the bedstead, consisting of a bell-lever c pivoted to the rigid frame f, a hand-lever b forming one arm of said bell-lever, an arm e hinged to the side a of the bedstead and pivoted to the other arm of said bell-lever, a connecting-rod d pivoted at one end to said handlever b, a second bell-lever c4 pivoted to said frame f having an arm pivoted to the other end of said connecting-rod d and an arm e hinged 1:0 the side cof the bedstead and pivoted to the other arm of said second bell-lever c4, all operating as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
